Luther called "justification" the doctrine upon which the church stands or falls. Even today the Gospel stands imperishable as a salvation by grace alone, through faith alone, in Christ alone (as known through the teaching of scripture alone) and to the glory of God alone. Let's never let it be compromised or obscured through mere tradition, human reason, fine sounding philosophy or that called knowledge which is not knowledge at all. Everything we need for our faith and life is found within the pages of the holy scriptures, the Bible, that our hope might rest in the true and living God.
